AUTOMATIC VENT-BUNG.

SPECIFICATION forming part of Letters Patent No. 263,063, dated August22, 1882. Application filed April 25, 1882.l (No model.)

To all whom it may concern:

Be it known that I, ADAMA E. ScHATz, a

citizen of the United States, residing at New York city, in the countyof New York and State of New York, have invented certain new and usefulImprovements in Automatic Vent- Bungs; and I do herebydeclare thefollowing to be a full, clear, and eXact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in automatic vent-bungs, and theobject is t0 permit atmospheric air to pass into the interior ofbarrels, casks, Sac., containing beer, ale, cider, and other iiuids orliquors, and thereby give a vent to them and assist in the withdrawal ofsuch fluids or liquors, and also to accom plish this in an automaticmanner.

The invention consists in the construction and arrangement of parts, aswill be more fully described hereinafter, reference being `had to theaccompanyingdrawingsand the letters of reference marked thereon.

Like letters of reference refer to like parts in the different figuresof the annexed drawings, in which- Figure l is a vertical cross-sectionof the improved bung attached to a barrel. Fig. 2 is a plan View ofthesame. Fig. 3 is a vertical cross-section of a modification of thesame.

' In the drawings, A represents a metallic bush, secured in any suitablemanner in th barrel or cask, and it is provided with lugs a, to hold theplate B in place. This plate B has notches b, which pass over the lugs cwhen it is to be placed in position, and by imparting a quarter-turn toit the plate is secured in its yseat under the lugs a by its edges,which have a gradual incline in the direction in which it is turned, andthus forms a tight joint against the face of the flange aof the blush.If desired, packing may be inserted between the edges of the plate andbush, usually, however, not necessary. The plate B is provided with araised portion, C, which is bored out or recessed to receive the head orbutton c of a washer or part, D, having a stem,l d, around The part ofthe plate B. Said disk is provided with one or more perforations for theadmission of air. When any liquid in the barrel, cask, Ste., iswithdrawn through the usual faucet the disk E, with part D, is drawninward by the vacuum created, andwill be immediately closed by thespring e, in addition to the force of the gases contained in the barrelwhen the faucet is closed.

In the modification shown in Fig. 3 the plate B is securedin the bush Aby a screwthread, tting into the screw threaded depression formed in thebush, while all the other parts are of the same construction as in Fig.l, and need no further description here.

Having thus described my invention, what I claim is- The combination ofa bush, A, plate B, hav

f, that bears against the inner side of the annu'lar dovetail projectiong on the under side ing recessed portion G, the head c, spring e, A

and valve-stem d, being within the recess, the washer D, and the rubberdisk E, provided with one or more perforations, as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
